1997 U.S. Open at Congressional Country Club
During the 1995 U.S. Senior Open, it was decided to use the existing par-three 18th for the time, but it was played out of order as the 10th. However, this proved to be logistically difficult, as there was a rather long walk around the lake to get from the 9th green to the 10th tee, followed by another as the players had to double back to get to the 11th tee following completion of the 10th. The USGA broke with tradition for the 1997 U.S. Open, and played the entire Blue Course in its original order and finished with the par-3 18th, which was the first time in history that the tournament had finished on a par-three. [My emphasis.]
The USGA was unsatisfied with their experiment, as most of the drama surrounding the 1997 Open had been decided at the 17th hole. With the creation of the new tour event in 2007 as well as the upcoming 2011 U.S. Open, it was decided to solve the problem once and for all. The club voted to permanently reverse the direction of the 18th hole, and Rees Jones was brought in to design a new par-3, which now plays in the opposite direction to the old 18th. The new hole now plays as the 10th, with the rest of the routing shifted so that the original par-four 17th hole now plays as the permanent 18th. A long walk from the new 10th green to the 11th tee remains, but not nearly as far as the old configuration.
